Prints out all the hard disk partitions in a easy to read manner. Improved version of df, written in python. Note that df shows only the mounted file systems or partitions and not all. To display only real disk partitions along with partition type, use df like this $ df -h -output=source,fstype,size,used,avail,pcent,target -x tmpfs -x devtmpfsįilesystem Type Size Used Avail Use% Mounted on Use grep to filter out real hard disk partitions/file systems. Only the file systems that start with a /dev are actual devices or partitions. The list generated by df even includes file systems that are not real disk partitions.įilesystem Size Used Avail Use% Mounted on dfĭf is not a partitioning utility, but prints out details about only mounted file systems.

So if you need to see the details of a particular disk, then pass the device name to cfdisk. Here is an example of how to use cfdisk to list the partitions.Ĭfdisk works with one partition at a time. It can be used to list out the existing partitions as well as create or modify them. Start: (c,h,s) expected (4,11,6) found (0,32,33)Įnd: (c,h,s) expected (1023,53,9) found (492,53,9)Ĭfdisk is a linux partition editor with an interactive user interface based on ncurses.

Sfdisk is another utility with a purpose similar to fdisk, but with more features. dev/sdb1 * 2048 7907327 3952640 b W95 FAT32Įach device is reported separately with details about size, seconds, id and individual partitions. I/O size (minimum/optimal): 512 bytes / 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes However it does not report the size of each partitions. The fdisk command can display the partitions and details like file system type. fdiskįdisk is the most commonly used command to check the partitions on a disk. Commands like fdisk, sfdisk and cfdisk are general partitioning tools that can not only display the partition information, but also modify them. ![]()
